Tony Jeffree led the IEEE 802.1 Working Group for 14 years, where he played a major role in editing numerous standards. Jeffree describes the early days of working in the evolving standards work of IEEE 802 in this part 1 interview with Ethernet Alliance chair Peter Jones for The Voices of Ethernet oral history archive.
Leading the IEEE 802.1 Working Group for 14 years, Tony Jeffree played a crucial role in editing numerous standards. In this part 2 interview, Jeffree continues his discussion on the importance of standards work with Ethernet Alliance chair Peter Jones for The Voices of Ethernet oral history archive.
Tony Jeffree: Ethernet as in ether type. Yes. Yes, indeed. That pretty much coincided with 802.5 disappearing from view because they were pretty the only people that cared about LLC surprise, surprise because they didn't have an ether dot in their frame format. And dot-3 and dot-1 didn't really much care about LLC. It didn't have any great value for us. In fact, it was a pain in the backside frankly. Yeah, I mean pretty much at the point where 802.5 became a non-protocol. Ethernet and using ether types for ethernet networks was the obvious way to go really.
Tony Jeffree: I'm on the Isle of Mull which is in the inner Hebrides just off the west coast of Scotland.
Tony Jeffree: Yeah. But that's fascinating in itself because it goes back in the days when the dot-5, dot-3 and dot-4 wars, come to that, were still in full flood. You know, people were saying that ethernet could never do real-time activities and that's patently not the case. You know, well, we had in the time that I was still at dot-1 a very active series of projects working on support for audio, video, and manufacturing and so on and so forth. It's a whole area that I'm sure will become very interesting in the coming years.
Peter Jones: Thank you so much. All right. So this is end of our story from Tony Jeffree. So tune in to hear the other Voice of Ethernet stories. And I look forward to seeing you on another videocast.
"Ethernet has been created by lots of contributors who all probably saw what was happening from a different point of view," David Cunningham said. "We've all worked on different parts of the standard at different times."
Cunningham's personal point of view is unusually comprehensive. In more than two decades of work in local and metro area network standardization, Cunningham contributed to some of the most important milestones in and even beyond Ethernet's evolution.
His entry into the technology space was "probably a little more accidental," he said. Cunningham is a laser expert who did his PhD work in spectroscopy. In 1987 he joined Hewlett-Packard at its laboratories in the United Kingdom and was tasked with helping develop a physical layer for a Gigabit-speed network using single-mode optical fiber.
"For my success, I got assigned to work on the FDDI (Fiber Distributed Data Interface) standard," he said. "… I didn't really know about multimode fiber, and I certainly didn't know about transmission over copper twisted pair."
